Add a docker-compose based local dev environment

[daniel-ac-martin]

Just use docker-compose up to start up the environment. You can
then access Keycloak on http://localhost:8080 and set it to use the
theme. Changes to the local files take effect without the need to
restart the server.

This might begin to address #1.

Alrighty, I’m on macOS 10.12.4, running Docker 17.03.1-ce-mac5 (16048).

I did this:

1. Switched to the local-dev-environment branch

2. Ran the shell command docker-compose up in the keycloak-theme-govuk root directory

3. Waited for Docker to download everything and bring everything up.

   The last messages I saw in the shell were:

    keycloak       | 11:53:04,115 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0060: Http management interface listening on http://127.0.0.1:9990/management
    keycloak       | 11:53:04,116 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0051: Admin console listening on http://127.0.0.1:9990
    keycloak       | 11:53:04,116 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0025: Keycloak 3.1.0.Final (WildFly Core 2.0.10.Final) started in 77762ms - Started 426 of 785 services (527 services are lazy, passive or on-demand)
   

4. Visited http://localhost:8080 (and, just in case, https://localhost:8080) in Chrome.

I got Chrome’s “This site can’t be reached: localhost refused to connect” screen.

Is there something else I should be doing to make this work?

I don’t think I have anything else running that listens on 8080.

Marvellous, thanks @daniel-ac-martin — I can now access Keycloak on http://localhost:8080.

I’ll look back at my notes and write up some docs on working with this project.
